TECHNICAL FIELD

The present invention relates to a compound which can form an organic thin film amenable to the selective alteration of its surface properties by light irradiation, in order to simplify patterning process in electronics products and to improve the reliability thereof, a compound which can use the corresponding physical change as a memory element, a production method thereof, and an organic thin film formed body prepared by forming the organic thin film containing the compound.

BACKGROUND ART

Compounds which form an organic thin film of which surface physical properties can be selectively changed by light irradiation to simplify a patterning process, although the process is generally complicated, in producing electronics products, and to improve the reliability thereof are known. With regard to a self-organized organic thin film of which surface physical properties can be changed by light irradiation, it is known in the prior art that the hydrophilic surface is formed following the cleavage of a silicon-carbon bond at a part irradiated with a laser beam at 193 nm on a thin film formed on a substrate by self-organization of an arylsilane compound or an aralkylsilane compound (Non-Patent Literatures 1 and 2).

It is also known that the surface physical properties of the predetermined part of self-organized benzyl phenyl sulfide film can be changed by photo-irradiation to make only unirradiated organic molecules part substitutable (Non-Patent Literature 3), and that at the surface of a self-organized film of a benzyl phenyl sulfone compound having a silicon terminal, which is formed from benzyl-4-(2-(chlorodimethyl silyl)ethyl)phenyl sulfone (Non-Patent Literature 4) synthesized by reacting 4-benzylsulfonyl styrene with chlorodimethyl silane in the presence of platinum catalyst, the absorption band due to the surface benzene ring is reduced by UV-irrdatiation along with the decrease of the wettability (Non-Patent Literature 5).

In contrast, it is described in Patent Literature 1 that a part of a hexamethyldisilazane film adsorbed onto a resist is selectively exposed to electron beams to eliminate it, followed by performing oxygen plasma treatment to etch only the film-eliminated part of the resist. A patterning in which the fluorine content is lowered by photo irradiation to a composite layer containing a photocatalyst and fluorinated part is disclosed in Patent Literature 2. A method for patterning composed of a hydrophobic part and a hydrophilic part by which an intermediate layer having light degradable activity is provided between an uneven base layer and a hydrophobic monolayer, followed by selective elimination of the hydrophobic layer by light irradiation is disclosed in Patent Literature 3. Moreover, application to a resist or a memory medium utilizing partial conformational change of a porphyrin-copper complex in its monolayer induced by exposing the layer to radiation including ultraviolet irradiation or heat is disclosed in Patent Literature 4. It is disclosed in Patent Literature 5 that a part of an organic molecular film can be eliminated by exposing it to ultraviolet irradiation between 200 nm and 380 nm. Moreover, it is disclosed in Non-Patent Literature 6 and Patent Literature 6 that 2-nitrobenzyl ester, or ether compounds containing terminal silyl group are useful as surface modifying agents which can lower the contact angle by ultraviolet irradiation.

Although self-organized organic thin films and organic molecular adsorbed films are utilized for patterning in the aforementioned prior art, the molecular structure thereof is limited, the use of photo-irradiation with high energy wavelength is required, and the molecular structure required for controlling film properties which is important to achieve reliability has not been sufficiently studied, and so they are not necessarily sufficient to achieve high reliability or photosensitivity. For example, the compounds disclosed in Non-Patent Literature 4 have a limitation to their molecular structure, because of their production method, and lack the variety of partial molecular structure required to produce an excellent film as disclosed in Non-Patent Literature 7.

Next, the produced sulfide compound (4) is oxidized by using a suitable oxidizing reagent to produce a corresponding sulfone (5). The sulfone (5) is then reacted with an alkylhalide or alcohol of which the terminal is olefin in the presence of a base or a condensation agent, to produce an olefin (6).

(Production Method 3) Production of a Compound in which X is a Mercapto Group, a C1 to C4 Alkylthio Group, or an Amino Group.

A compound (1-3) in which X is a mercapto group, a C1 to C4 alkylthio group, or an amino group can be produced by reacting the compound (5) with α, ω-dihaloalkane to produce the compound (7), followed by nucleophilic substitution reaction with a sulfur or nitrogen atom.

(Production Method 4) Production of a Compound in which X is a Disulfide Group.

A compound (1-3) in which X is a disulfide group can be produced by oxidatively dimerizing a compound in which X is mercapto group.

(Production Method 5) Production of a Compound in which k is 0.

This can be produced in accordance with the aforementioned production methods 1 to 4 for introducing X by using a compound produced by alkylating only one hydroxyl group of 4,4′-dihydroxydiphenyl sulfone used as a starting material, and by reacting the other hydroxyl group with an alkylating agent of which the terminal is an olefin or a halogen atom.

(Organic Thin Film Formed Body)

An organic thin film formed body according to the present invention is characterized by being prepared by forming an organic thin film by coating on a surface of a substrate a solution containing a compound represented by the aforementioned formula (1) (hereinafter, referred to as “compound (1)”).

There are no particular limitations imposed on the substrate used, provided that it can allow formation of an organic thin film containing compound (1). Examples thereof include glass substrates such as a soda lime glass plate, and the like, substrates on which surface electrodes are formed, such as ITO glass and the like, substrates on which surface insulating or conductive layers are formed, silicon substrates such as silicon wafer substrates, and the like, ceramic substrates, and the like. It is preferable that the substrate be used after cleaning by using ozone; ultrasonic waves; distilled water, ion-exchanged water, detergent such as alcohols, or the like.

There are no particular limitations imposed on methods of forming an organic thin film containing compound (1) on the surface of the substrate. Examples thereof include a method by which a solution containing compound (1) is coated onto the substrate in accordance with a conventional coating method, followed by heating and drying the coated film. Examples of the coating method include coating methods using a conventional coating apparatus, such as a dipping method, a method using a spin coater, a method using a dye coater, a spraying method, and the like.

There are no particular limitations imposed on the solvents in which compound (1) is dissolved, provided that they are inert for compound (1) and can dissolve it. Examples thereof include aromatic hydrocarbons such as benzene, toluene, xylene, and the like; aliphatic hydrocarbons such as pentane, hexane, and the like; cycloaliphatic hydrocarbons such as cyclopentane, cyclohexane, and the like; esters such as methyl acetate, ethyl acetate, and the like; ethers such as diethylether, diisopropylether, 1,2-dimethoxyethane, THF, 1,4-dioxane, and the like; and ketones such as acetone, methylethylketone, methylisobutylketone, cyclohexanone, and the like.

After coating the film containing compound (1), it is preferably heated at 100 to 200° C. to remove the solvent to finish forming of the film. Moreover, it is preferable that solvent cleaning be carried out to remove organic molecular multilayers. Although there are no particular limitations imposed on the thickness of the produced organic thin film, it is usually approximately 1 to 100 nm.

The produced organic thin film has physical properties modified by light irradiation. For example, only an irradiated portion is changed to a hydrophilic thin film by ultraviolet irradiation. This change can be confirmed by, for example, measuring the change of contact angle against water. Thus, only the specific portion of a resist film which is prepared with a predetermined pattern after forming the organic thin film containing compound (1) on the substrate can be changed to a hydrophilic thin film by exposing the portion to ultraviolet light.

EXAMPLE 6

Formation of an Organic Thin Film

An organig thin film was prepared from the solutions of compounds Nos. 2, 3, and 43. A representative method is as follows. The compound was diluted with anhydrous toluene as its concentration was 0.5% by weight in each case. A substrate, namely soda lime glass or silicon wafer which was pre-cleaned as cited below, was immersed into above solution for 10 minutes, and baked at 150° C. for 10 minutes. Then its surface was washed by immersing it in toluene with ultrasonic irradiation to remove over-layered adsorbed ingredients, and the resulted substrate was dried at 60° C. for 10 minutes to give an organic thin film of the compound.

Pre-Cleaning of Substrates

The substrate was washed with detergent with ultrasonic irradiation, with ion-exchanged water, and with ethanol, followed by drying at 60° C. then treated with UV/03 cleaner before immersion.

EXAMPLE 7
